Impact of Polymer Modification on IDEAL-CT and I-FIT for Balanced Mix Design
| 项目名称： | Impact of Polymer Modification on IDEAL-CT and I-FIT for Balanced Mix Design |
| 摘要： | The overall objective of this study is to determine the impact of polymer modification on the IDEAL-CT (Indirect Tensile Asphalt Cracking Test) and I-FIT (Illinois Flexibility Index Test) results for balanced mix design. Specifically, the study seeks to evaluate two hypotheses for the unexpected IDEAL-CT and I-FIT results indicating better intermediate-temperature cracking resistance for unmodified mixtures than polymer modified asphalt mixtures. The first hypothesis is related to lack of optimization of asphalt binder content in the mixtures tested, while the second hypothesis is related to the limitation that the current IDEAL-CT and I-FIT procedures cannot appropriately demonstrate the benefits of polymer modification. |
